Hybrid oven

ABSTRACT

A hybrid oven comprising an oven case; an upper cover is hinged on an upper part of the oven case; wherein a control panel is provided at an upper part of a front surface of the oven case; a lower part of the oven case is provided with an oven; a back panel inside the oven is provided with electrical heating elements; a bottom part inside the oven is provided with gas heating elements; the electrical heating elements and the gas heating elements are electrically connected to the control panel.

BACKGROUND OF THE INVENTION

The present invention relates to an oven, and more specifically relatesto a hybrid oven which can utilize both gas and electricity for heating.

Ovens currently available nowadays are usually mono-functional in thatthey are either electrical ovens or gas ovens. Gas ovens can be heatedup quickly but the heating temperature cannot be effectively controlled.On the contrary, electrical ovens have a precise control over heatingtemperature, but they can only be heated up slowly and they also consumea large amount of energy. These two ways of heating cannot beeffectively combined and sufficiently utilized according to the existingprior arts.

BRIEF SUMMARY OF THE INVENTION

In view of the aforesaid disadvantages now present in the prior art, thepresent invention provides a hybrid oven. The present invention canachieve double and complementary heating effect by both electricalheating and gas heating, thereby enhancing heating effect andefficiency. Also, the hybrid oven of the present invention can stilloperate with the availability of either electricity or gas, if not both.

The present invention employs the following technical scheme:

A hybrid oven comprising an oven case; an upper cover is hinged on anupper part of the oven case; gas stove heaters are provided below theupper cover; a control panel is provided at an upper part of a frontsurface of the oven case; a lower part of the oven case is provided withan oven; a back panel inside the oven is provided with electricalheating elements; a bottom part inside the oven is provided with gasheating elements; the electrical heating elements and the gas heatingelements are electrically connected to the control panel.

The back panel inside the oven is provided with a temperature controldevice.

The bottom part inside the oven is provided with another temperaturecontrol device.

An air passage is provided between the oven and the oven case; the airpassage is in communication with the electrical heating elements and anouter environment exterior to the oven case; the electrical heatingelements comprise a heating pipe, an even heat distribution fan disposedat a back side of the heating pipe, and a fan cover through which theheating pipe and the even heat distribution fan are fixed on the backpanel.

The gas heating elements comprise a lower flame channels main gas pipe;the lower flame channels main gas pipe is provided with flame channelsblocking panels on two sides; the lower flame channels main gas pipe isfixed to the bottom part of the oven via a flame channels bracket; aflame guiding tray, a cooking tray and a grid tray are mountedsequentially from bottom to top above the lower flame channels main gaspipe and the flame channels blocking panels.

The technical scheme of the present invention has the followingadvantages:

The electrical heating elements are mounted on the back panel at theback inside the oven; an even heat distribution fan is used forenhancing the heating effect of the heating pipe; gas heating elementsare mounted on the bottom part inside the oven so that heating by theuse of gas is achieved based on the principle that flame will burnupward; also, the oven is heated up by using temperature control at thebottom part and in the middle of the back of the oven at the same time;the characteristics of quick heating by gas and the characteristics ofprecise heating by electricity are fully utilized to quickly achieve thedesired cooking temperature and lower the energy consumption and savingtime and effort during cooking procedures.

Further, even under the availability of only one power source, meaningthat either gas or electricity is available, but not both, the oven canstill be used for cooking. In this case, the equipment is fully utilizedby its capability of being powered by different power sources.
